With a Step Down transformer. But you will probably have a hard time finding a 240 volt unit. 120 volts units are readily available.

It depends on how big of a transformer that you are looking for. There are many control Transformers in the 50 to 500 VA range that have dual primary and dual secondary. The primary side can be connected to 240 volt or 120 volt and the secondary can be connected for either 12 or 24 volts.
Changing from one voltage to another is quite simple... if you have AC. This conversion is done with a transformer. In the situation described, where you start by DC, you need to convert from DC to AC first, so that you can use a transformer. A device which does this is called a "power inverter" or simply an "inverter". The Wikipedia article on "Power inverter" explains some ways such a circuit can be designed.
You would need a transformer specially made to do this. Of course, this transformer would need a rectifier, as I am assuming that you need 12 volts DC.
with the correct transformer rated to convert 240volt to 12volt
Buy an inverter with the voltage and power specification per your application. There are lots of sources on the Web.
There in no quick and inexpensive way of doing this conversion. A transformer would have to be used and this type of winding is not common. 277 volts is the wye voltage of a three phase 480 volt system.
Yes, 220 volts is in the same voltage classification as 230 volts.
Yes, but a fact has to be taken into account that when a 230 volt rated bulb is used on a 120 volt system the wattage output is half of what the 230 volt bulb is rated at when it operates on 230 volt. So the dimmer will only be used to control half of the bulbs wattage which could bring the bulb down to a dull glow in full dimming position.
If it is a 12 volt panel it will light a 12 volt bulb. Most likely it is not a 12 volt panel, it is some other voltage, so you then need equipment like an inverter to convert the energy to 12-volt energy.
230
That is called an inverter.
If a precision voltage is needed from 200 to 230 an auto transformer could be used. If the load is a 230 volt motor to be operated on 200 then add 15% to the nameplate full load amperage for the calculation for overload protection.
Yes, you can use a 230 volt device on a 240 volt supply.
A 12 volt battery will not hurt you BUT any POWER supply (especially a 230 Volt one) has the potential to harm you.
The only way to do that is with a transformer. They make inline transformers that convert 230 to 115 and they simply plug in inline.
Unless otherwise specified, all a.c. voltages and currents are expressed in root-mean-square (rms) values. An rms value is exactly equivalent to a corresponding d.c. value. So, 230 V a.c. is exactly equivalent to 230 V d.c., and 10 A a.c. is exactly equivalent to 10 A d.c.Incidentally, the symbol for volt is 'V' (not 'v') and the symbol for ampere is 'A' (not 'a').
Use a voltage devider or a transformer.
It can be done with 90% efficiency.
no
Converting 9 volts to 230 volts would require a pretty hardcore step up transformer (Expensive) and you probably wouldn't have enough current to sustain the load.See discussion page for more information.
No.
With an appropriately rated DC to DC converter.
